Know Your Teammates
Know Your Teammates is a free team building game for 3-20 players that can be played in a browser.
It has two phases: during collection phase, the players are asked to enter 3-5 facts about themselves, eg. hobbies, books, movies they enjoy, places they have visited or other fun facts. In play phase, one fact is presented to all players and they have to guess who wrote it. The real fun is in the discussion following it :-)
